Abstract (en)
[origin: WO9623853A1] High-vacuum oil refinery systems and process are disclosed in this invention. The systems and process enable to carry out vaporization and distillation of oils under the condition of 1 - 10-4 Torr of high vacuum and at the temperature of not higher than 360 DEG C avoiding thermal cracking while heating to be vaporized to produce high quality oil. The vaporized gases are centrifugally separated and liquefied by using high-vacuum gas specific gravity centrifugal separators. The process of vaporization and distillation is carried out at temperatures below 360 DEG C preventing vaporization of sulfur components of the oil, which are drained along with the concentrated sludge oil thus distilling and desulfurizing the crude or heavy oil simultaneously without using expensive conventional desulfurizing process. Especially the pressure reduced thermal cracking device performs the oil cracking works under the pressure reduced environment which enables to save more than 50 % of the cost comparing with the conventional high pressurized oil cracking facility.
